ae03c0a6bf drivers: spi_nrfx_spi: initialize all cs gpios during init
In case when we have multiple devices connected to the
one SPI interface the initial state of CS gpios after
MCU reset is floating and it might be low that prevents us from
communicating between particular devices. Fix that by
initializing all provided cs gpios and setting them as inactive.

eafafa2816 drivers: spi_nrfx_spis: Fix handling of buffer lengths
Do not limit the length of the prepared transfer to the shorter of
provided TX and RX buffers if both are used. The SPIS peripheral
cannot handle scattered buffers anyway, so there is no point in
getting the common part of TX and RX buffers for a partial transfer,
like it is done for SPI and SPIM peripherals; everything what is
possible needs to be transferred in one shot. For the same reason,
there is no point in calling spi_context_buffers_setup() and using
the related part of the spi_context structure, hence the call is
removed and buffer pointers are used directly.
Also return an error if a requested transfer length exceeds the SPIS
peripheral hardware limit, instead of silently limiting the transfer
like it was done so far.

According to the nRF5340 PS, for 32 Mbps high-speed SPI using SPIM4,
drive configuration H0H1 must be used. The underlying nrfx_spim driver
does it properly in its initialization function, so change the shim to
(re)initialize the driver when the SPI configuration is to be changed
(only then the speed to use is known), to avoid the need of duplicating
the corresponding code in the shim itself.

7ccc1a41bc pm: use actions for device PM control
Instead of passing target states, use actions for device PM control.
Actions represent better the meaning of the callback argument.
Furthermore, they are more future proof as they can be suitable for
other PM actions that have no direct mapping to a state. If we compare
with Linux, we could have a multi-stage suspend/resume. Such scenario
would not have a good mapping when using target states.

56a35e5682 pm: converge to suspend state for low power modes
The difference between low power and suspend states is a thin blur line
that is is not clear and most drivers have used indistinctly. This patch
converges to the usage of the suspend state for low power, since
contrary to the low power state, it is used by both system and runtime
device PM. The low power state is still kept, but its future is unclear
and needs some discussion.
